1 Scope This document specifies requirements, test methods and compliance criteria for cement bound granular mixtures used for construction and maintenance of roads, airfields and other trafficked areas. This document specifies the characteristics of cement bound granular mixtures (CBGM) by reference to the properties of their constituents, the mixture and the properties of specimens of the mixed materials.

= 0,60; Rt28/Rt360 = 0,60 and E28/E360 = 0,65, where the superscripts represent the age at test, in days, when specimens have been cured at 20 °C. 5.3 Aggregate 5.3.1 Type of aggregate The aggregates shall comply with EN 13242. They shall be either crushed or uncrushed or a combination of both. They shall be of the following type: a) naturally occurring or artificial aggregate, or b) recycled construction aggregate, or c) a combination of a) and b). The chosen proportions shall be specified in the contract and maintained to a tolerance of ± 5 % by mass related to the declared proportions. 5.3.2 Grading curve of the aggregate The aggregate grading for a specific mixture shall be selected within the envelope of Figure 1. This aggregate grading shall be used to establish the job standard mix. NOTE 1 The envelope in Figure 1 may further be limited taking into account the rules in use at the place of use, e.g. by national regulations. Annex B gives examples of grading limits which have been found to be appropriate in some locations. NOTE 2 The envelope in Figure 1 covers all gradings with which practical experience in cement bound granular mixture exist. The sub-envelopes A and B are informative only. Gradings characterised by envelope A include sands, which have been found in some locations to be able to be successfully compacted and capable of fulfilling the requirements of this document. Grading classified by envelope B includes well-graded coarse aggregates with limited contents of fines <0,063 mm. SIST EN 14227-1:2005

5.3.3 Harmful fines The aggregate shall not contain harmful fines in a quantity that affects the hardening, the strength or the durability of the mixture. 5.4 Additions If ground granulated blast furnace slag is used, it shall conform to a European Technical Approval or to national regulations. It shall also be incorporated in the design of the job standard mix. Where fly ash is to be used it shall be part of a blended cement conforming to EN 197-1. Mixtures containing cement and fly ash, which is added on site during or immediately prior to mixing with the aggregate, shall conform to EN 14227-3. 5.5 Mixing water The mixing water shall conform to EN 1008. SIST EN 14227-1:2005

6.2 Binder content The binder content of the mixture (job standard mix) shall be determined by a design procedure and/or experience with mixtures produced using its proposed constituents. Design procedures shall conform to national regulations or to provisions valid at the place of use. The binder content shall not be less than the minimum
